I took my son to work and we were a bit early so i was looking up through my sunroof at these whispy clouds when i noticed a silvery orb. it was moving forward in a very deliberate manner, then started emitting this sort of chemtrail before just disappearing. a minute or two later a commercial airliner flew through the same airspace and it was instantly recognizable. the chemtrail was as thick and heavy as one from a military jet, but was very short, like maybe a football field or two long. but the orb was nowhere near as big as a jet. it wasn't big enough for that kind of chemtrail. i don't think a drone could do that either, and then just disappear into thin air.
